grammar_cop is a standalone ruby extension for the link-grammar-4.7.4 C library. You don’t have to install anything extra, so this is deployable on platforms like heroku, cloudfoundry. Example:

require ‘grammar_cop’

puts dir = File.expand_path(‘../data’, File.dirname(__FILE__)) GrammarCop::Dictionary.set_dictionary_path(dir)

dict = GrammarCop::Dictionary.create(“en”) opts = GrammarCop::ParseOptions.create text = “Grammar is useless because there’s nothing to say – Gertrude Stein.” sentence = GrammarCop::Sentence.create(text, dict) puts num = GrammarCop::Sentence.parse(sentence, opts) if num > 0

linkage = GrammarCop::Linkage.create(0, sentence, opts)
puts GrammarCop::Linkage.create_diagram(linkage)
puts "sublinkages=#{GrammarCop::Linkage.sublinkages_count(linkage)}"
puts "num_words=#{GrammarCop::Linkage.num_words_count(linkage)}"
puts "num_links=#{GrammarCop::Linkage.num_links_count(linkage)}"
#GrammarCop::Linkage.destroy(linkage)

end GrammarCop::Sentence.destroy(sentence)
